I am intrigued by the SIG 556 R in 7.62x39. I like the round better than 5.56 and I like the "look and feel" of the Sig 556. How do they function? How do they hold up? I am not looking for an AR-15 or another AK. I was wondering if anyone who has one of these, or has fired one (or even the 5.56 version) could provide me with information I can't get from the manufacturer.

Wow. That's really what I have been looking for now that RRA is almost certainly dumping the LAR-47 build. I had no idea Sig made such a weapon. Now the insanely difficult challenge of finding one before the SHTF...

Early ones had reports of reliability problems and the steel AK mags were tearing up the aluminum receivers. I have "heard" the newer ones have been corrected. You may want to research more before you buy. I have a 556 in .223 and am happy with it.

I will be using polymer mags but thanks for the heads up! I will be doing some research. I don't need anymore 5.56 ARs.

I just spent an hour reading about the two similar options out there... Both the XCR in 7.62 and the 556R have way to many bad reviews if you ask me. I think there is a reason Robinson isn't listing the 762 anymore on their website.

The 556R will not shoot Wolf ammo nor will it accept a steel mag without doing obvious damage to the weapon over a short period. I did read the one review from Warrior Talk that stated it would shoot anything in terms of ammo, but I have read many noting failures. Plus, Sig says they will void your warranty to shoot steel casing. I think I will stick with my ARs for now. I really wanted a fighting rifle in 7.62x39 that would run steel casings if necessary, but that doesn't appear to be a possibility at this time.

That's the "gen one" rifles. The new ones have a steel insert to protect the receiver from wear by the magazines. And SIG says you can shoot any 7.62x39 in the new one.

I know, if you do a google search you find lots of critical reviews and lots of problems. But look at dates. I don't actually own one so I'm just telling you what I've observed online. The newer ones are worth owning. I would take one anytime. Maybe I'll get the chance someday if the chaos ever goes away!

I've shot two 556Rs---both were properly maintained (my buddy and his dad have them and take care of their guns) and both were unreliable and had various issues. I would stay far, far away from them; especially when there are so many quality AKs that are proven and priced similarly or less (maybe not these days ).

Did they have the generation 2 "updates"? How long ago did you shoot them?

I've got one, a 2nd generation. I've put about 350 rounds through mine, and I really like it. No problems at all with the carbine itself, though I had some minor feeding issues with a Tapco magazine. I've used steel AK mags in it (Hungarian 20 round). Worked fine.
